The Netherlands have joined you. People are terrified of terrorism. Look what happened 2 days ago, while there was a ceremony to honor the people who died in WW2.
One homeless drunk started screaming, the rest got scared and tried to get out as fast as possible. Nobody died, but at around 65 people broke a leg or wrist.
When the guy started shouting, people were reminded of Queen's Day of last year, where a guy drove in on a crowd, killing about 8 people.
Here's some shocking amateur images if you want to see it. Warning: you'll see dead people.

Last year's attack was terrible. This year, nothing really happened. Is fear a bigger enemy than terrorism?
(Edit: I forgot about the Politics forum, maybe move it there? Thanks.)
